1/3907. Primary carcinoma of the colon and hyperlipemia: a paraneoplastic syndrome.

    The human counterpart of the association of hyperlipidemia with cancer is rare, as compared with the relative frequency of the syndrome in experimental animals. A case is presented of adenocarcinoma of the colon with a non casual relationship between the presence and the progression of the tumor and hyperlipemia. Surgical resection and antiblastic chemotherapy moreover seemed to influence the metabolic anomaly.

2/3907. Clinical value of protein-bound fucose in patients with carcinoma and other diseases.

    Protein-bound fucose content in sera from normal persons and patients with various malignant and non-malignant diseases was measured and statistically analyzed. Normal serum gave a mean value of 6.84 /- 0.13 mg/100 ml, and rarely exceeded 9 mg/100 ml. Although no significant difference was found between sexes, there was a tendency of fucose content to decrease in older persons. It was noted that more than 90% of cancer-bearing patients have significantly higher level than critical value (9 mg/100 ml), while only 8.7% of patients with benign tumor showed positive result. These results were not limited to special organs but in common to all cases studied. The elevation of serum fucose content in malignant tumor was well correlated with its stages of progression, though the levels were less significant in early and in rather locally restricted breast and thyroid cancer. Serial postoperative follow-up study showed that the levels in serum fucose content was a useful parameter for judging the effectiveness of therapy and the prognosis of the patient. The fucose content in malignant tumor tissue and metastasized lymph node appeared to be significantly elevated than that in normal tissue. The practical usage and limitation of the fucose value in various diseases, together with a possible source of serum fucose were discussed.

3/3907. Mandibular metastasis in a patient with endometrial cancer.

    Gynecologic cancers metastatic to bone are a rare entity, and a metastasis to the mandible at initial presentation is even more infrequently seen. We present a case of a 71-year-old woman with stage IV endometrial cancer with a metastasis to the mandible, with no other sites of distal spread apparent. The endometrial tumor was a FIGO grade III adenocarcinoma. The pathologic evaluation of the mandibular lesion revealed poorly differentiated adenocarcinoma with focal squamous differentiation. She was treated with a total abdominal hysterectomy and bilateral salpingo-oophorectomy, radiation therapy to the mandible, and chemotherapy consisting of Taxol and carboplatin for six cycles. She had a complete response, but 10 months after the original diagnosis developed spinal cord compression and progressive disease in the pelvis. patients in good clinical condition with a single bone metastasis should be treated aggressively, as survival can be extended.

4/3907. A case of leptomeningeal metastasis from lung adenocarcinoma diagnosed by reverse transcriptase-polymerase chain reaction for carcinoembryonic antigen.

    A case of leptomeningeal metastasis from lung adenocarcinoma is reported. In this case, we evaluated the feasibility of reverse transcriptased polymerase chain reaction (RT-PCR) methods to detect cancer cells in cerebrospinal fluids (CSF). Messenger rna of carcinoembryonic antigen (CEA) was clearly demonstrated in CSF by reverse RT-PCR methods. An immunohistochemical study also demonstrated that tumor cells were stained positive with anti-CEA antibody. This case suggests that RT-PCR for CEA was a sensitive and useful method to diagnose leptomeningeal metastasis from lung adenocarcinoma.

5/3907. An extrahepatic bile duct metastasis from a gallbladder cancer mimicking Mirizzi's syndrome.

    We report a case of an extrahepatic bile duct metastasis from a gallbladder cancer that mimicked Mirizzi's syndrome on cholangiography. A 67-yr-old woman was admitted to our hospital with a diagnosis of acute calculous cholecystitis. As obstructive jaundice developed after the admission, percutaneous transhepatic biliary drainage was performed to ameliorate the jaundice and to evaluate the biliary system. Tube cholangiography revealed bile duct obstruction at the hepatic hilus, and extrinsic compression of the lateral aspect of the common hepatic duct, with nonvisualization of the gallbladder. No impacted cystic duct stone was visualized on CT or ultrasonography. laparotomy revealed a gallbladder tumor as well as an extrahepatic bile duct tumor. We diagnosed that the latter was a metastasis from the gallbladder cancer, based on the histopathological features. This case is unique in that the extrahepatic bile duct metastasis obstructed both the common hepatic duct and the cystic duct, giving the appearance of Mirizzi's syndrome on cholangiography. Metastatic bile duct tumors that mimic Mirizzi's syndrome have not been previously reported. The presence of this condition should be suspected in patients with the cholangiographic features of Mirizzi's syndrome, when the CT or ultrasonographic findings fail to demonstrate an impacted cystic duct stone.

6/3907. Primary anaplastic giant cell adenocarcinoma of the larynx.

    Anaplastic giant cell adenocarcinoma is an extremely rare tumour arising in the bronchial mucosa. This report describes an example--the first to be reported--of such a tumour evidenced in the subglottic region in a 64-year-old man. Histologically, the tumour resembles that arising in the lung and its morphological characteristics justify a distinction of anaplastic giant cell adenocarcinoma from other types of laryngeal malignant epithelial tumours. As to its histogenesis, the neoplasm is most probably of glandular origin and should be considered as a dedifferentiated adenocarcinoma. The patient, who had undergone total laryngectomy followed by X-ray treatment, is alive one year after surgery.

7/3907. A Val 677 activating mutation of the thyrotropin receptor in a Hurthle cell thyroid carcinoma associated with thyrotoxicosis.

    Thyroid nodules presenting as hot at 131I-scintigraphy are usually benign follicular adenomas. We report a 42-year-old female patient with an autonomously functioning Hurthle cell thyroid carcinoma causing thyrotoxicosis. Genetic analysis of her thyroid tumoral dna revealed a heterozygotic activating mutation of the thyrotropin receptor (TSHR) gene that was located downstream to all of the other genetic alterations currently identified, and is due to a base substitution at codon 677 (normal cytosine replaced by guanine, CTG for GTG causing leucine substitution by valine in the seventh transmembrane domain of the receptor). This mutation was detected in the tumor, but not in the leucocytes from the same patient. The Val 677-TSHR mutant showed constitutive activity, in terms of cyclic adenosine monophosphate (cAMP) production, when permanently transfected in Chinese hamster ovary (CHO) cells. Gsp and ras oncogenes and the p53 tumor suppressor gene were not present in the Hurthle cell cancer. The TSHR mutation in this Hurthle cell carcinoma may be responsible for maintaining differentiated thyroid function and hyperthyroidism.

8/3907. Interposition of sural nerve restores function of cavernous nerves resected during radical prostatectomy.

    PURPOSE: The permanent loss of erectile function when both neurovascular bundles are widely resected at radical prostatectomy as well as the successful use of autologous nerve grafts in reconstructive surgery led us to perform bilateral nerve grafts in an effort to restore erectile function in potent patients treated for prostate cancer who underwent radical retropubic prostatectomy and resection of both neurovascular bundles. MATERIALS AND methods: Radical retropubic prostatectomy with deliberate resection of both neurovascular bundles was recommended for high grade, locally extensive prostate cancer in 9 select, sexually active men who reported normal erectile function. After the prostate was removed but before vesicourethral anastomosis an autologous sural nerve graft was interposed between the divided ends of the cavernous nerves bilaterally. Erectile function was monitored by patient interview, questionnaire and nocturnal penile tumescence testing after the operation. RESULTS: Four to 5 months postoperatively patients noticed slowly improving spontaneous erections, as manifested by mild tumescence regularly every several hours. Nocturnal penile tumescence testing with the RigiScan device at 4 to 6 months in 2 cases revealed erections that approached minimal criteria for normalcy. Approximately 14 months after surgery a rigid erection sufficient for penetration and intercourse developed in 1 patient. He described this event as "an erection of substance-hard, not just fluffy." CONCLUSIONS: We have developed a technique using sural nerve grafts to restore continuity of the cavernous nerves, which are resected during radical prostatectomy. The early return of spontaneous partial erections in our patients suggests that interposition nerve grafts may enhance the recovery of erectile function when the neurovascular bundles are resected.

9/3907. Hurthle cell carcinoma of the thyroid gland with extensive tumor necrosis: a case report.

    Hurthle cell neoplasm of the thyroid gland is rarely associated with tumor necrosis. We report a case of Hurthle cell carcinoma of the thyroid gland with extensive necrosis. An 82-year-old man had had a right neck mass for more than 10 years. Approximately two to three weeks before he was hospitalized, this neck mass became progressively enlarged. An 131I scan could not demonstrate the right lobe of the thyroid gland, while the contralateral lobe was unremarkable. A 99mTc-sestamibi scan showed increased uptake on the lesion side. Fine needle aspiration cytology showed necrosis with macrophages in the initial aspirate, and the secondary aspirate appeared suspicious for a Hurthle cell tumor. The patient had a total thyroidectomy, and the pathology proved to be Hurthle cell carcinoma with tumor necrosis.

10/3907. Unexpected gallbladder cancer after laparoscopic cholecystectomy: an emerging problem? Reflections on four cases.

    gallbladder cancer (GC) has been reported in 0.3-1.5% of cholecystectomies. Since the introduction of laparoscopic surgery, cholecystectomies have increased and occult GC may therefore be more frequent. Herein we analyze our own experience to determine whether there was an increase in GC. We also evaluate the risk factors for this outcome. Four patients with GC undiagnosed before surgery (four of 602 cases, or 0.66%) were submitted to laparoscopic cholecystectomy. The percentage in patients who underwent open surgery was 0.28% (two of 714 cases). Without reoperation, three patients died in the laparoscopic group and one is alive at 12 months. Trocar site metastasis was not observed. Although the percentage of GC (0.28% versus 0.66%) increased, the percentage is still in the referred average. Undiagnosed GC is on the increase. Examination of the gallbladder and a frozen section, if necessary, are recommended. Calcified gallbladders, age >70 years, a long history of stones, and a thickened gallbladder all represent significant risk factors.
